Battery Care Tips
Battery Care Tips
🔹 Getting Started
Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.
🔹 Keep It Healthy
Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.
Delivery and Shipping
Delivery and Shipping
🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

HP Mini 1000 Series — 11.1V Li-ion Replacement Battery (493529-371)
This is an 11.1V, 4400mAh (48.84Wh) Li-ion battery for the HP Mini and Mini 1000 series notebooks. It replaces OEM part numbers including 493529-371, HSTNN-XB80, HSTNN-OB80, and 504610-001. Fits Mini 1001, Mini 1001TU, and over 130 additional Mini variants sharing the same connector and voltage rail.
- Mini series platform fit: These models share a common 11.1V three-cell architecture, identical BMS handshake protocol, and the same physical connector. One cell fits all variants listed — no adapter or wiring change required.
- Bench tested on actual hardware: We ran this cell on a Mini 1000 unit and confirmed the BMS completed charge handshake, accepted full CC/CV charge to 12.6V, and reported cell status correctly through the OS fuel gauge IC.
- First-cycle calibration on HP Mini: After installing, run one full discharge to hibernate-cutoff, then charge uninterrupted to 100%. HP Mini's BIOS battery learn cycle requires this to clear the inaccurate health warning that appears after every cell swap.
BIOS reporting poor battery health immediately after installation
The HP Mini BIOS reads EEPROM data embedded in the battery cell. A new cell carries factory EEPROM values that don't match the BIOS's stored charge history from the old battery. This mismatch triggers a health warning that looks like a fault but isn't. Run one complete discharge-to-hibernate cycle followed by an uninterrupted charge to 100% — that sequence resets the learn cycle and clears the warning on most Mini units.
Laptop shuts down at 20–30% charge shown on screen
This happens when the fuel gauge IC hasn't been calibrated against the new cell's actual discharge curve. The IC is still referencing voltage thresholds from the depleted old cell, so it reads 20–30% but the cell voltage is already dropping below the safe cutoff under CPU and display load. Run two to three full discharge-to-charge cycles without interruption. After calibration, the gauge will track the new cell correctly and shutdowns at false-high percentages stop.

Frequently Asked Questions
The HP Mini BIOS shows my new battery as "unknown" or 0% — is the cell dead?
No — the BIOS is reading stale EEPROM data that doesn't match the new cell. This is a calibration state, not a fault. Plug in AC power, let the battery charge uninterrupted to 100%, then discharge fully to hibernate-cutoff. After one complete cycle the BIOS learn cycle resets and the reading corrects itself.
My HP Mini's battery meter jumps around wildly for the first few charges — what's causing that?
The fuel gauge IC inside the Mini calculates remaining charge by comparing real-time cell voltage against a learned discharge curve. After a cell swap, it has no valid curve for the new cell and produces erratic readings. Run two to three uninterrupted full discharge-to-charge cycles — the IC builds an accurate curve against the 4400mAh cell and the jumping stops by cycle three.
Windows is showing this battery's capacity as lower than the 48.84Wh listed — why does the Wh figure look wrong in system info?
Windows reads the rated Wh value stored in the battery's EEPROM, which reflects factory-programmed figures and may differ slightly from the calculated 48.84Wh derived from the actual cell chemistry. This is a reporting difference between stored EEPROM data and real cell capacity — it does not affect how the battery charges or discharges. Check actual behaviour over two full cycles rather than the system info figure.
